A Festival can last 1 month or 2 weeks or 8 days, and each day players can win a festival chest by collecting 15 crowns in festival battles.

Festival chests contain a random collection of festival currency, resulting in roughly 300-500 currency per chest. The currency, which varies for each festival, is exclusive an can only be used to buy items from Festivals. On rare occasions, festival chests also contain a Set item. Festival chests can also be bought with gems.
